SPECIFICATION forming part of Letters Patent No. 705,791, dated July 29, 1902. Application iiled December 10,` 1901. Serial No. 85,350. (No model.)4

To all whom, it may concern,.- Y

Be it known that I, JAMES ROURKE, a' citi zen of the United States, residing at Parkersburg, in the county of Wood andl State of West Virginia, have invented certain new and useful Improvements in Portable Drilling` Machines, of which the following is a specication. l

My invention relates to that class of portable drilling-machines which are used for drilling oil and Artesian wells, and has for its object to provide a machine which is of simside elevation of the sandreelfriction-pulley' and its operating-lever. Fig. is ``a `detail sectional viewwof thesame. Fig. `6 is a detail' view,partly in section andpartly in elevation, showing the structure of4 thesprocket-Wheel and means for securing same tothe bull and brake wheels. Fig. GfL is an insideview of the bull-wheel sprocket. Fig. 6b is a viewyon line b b, Fig. 6, showing the bracing-arms for the bull-Wheel. tional Views of the clutch and clutch-operating mechanism, Fig. 7 being a view on the line 7 7, Fig. 7 a; and Fig. 8 is a detached view of the righ-ame.

Similar reference -numerals denote like parts throughout the several views.

1 represents mudsills.

2 represents crosssills keyed into the mudsills l and upon which rests the rig-frame, which consists of two sides, the f ront or crank side Ycomprising a lower sill 3, gained in and bolted to the cross-sills 2.

Il represents upright posts mortiscd in the lower' sill Eiland provided Awith tenons at their tops, which are` mortiscd into the plate 5, which is also bolted to the lower sill 3. Carriedby said plate 5 is a pillow-block 6,Which provides a bearing for the crank-shaft 7. The plate lalso carries the frame 8, on which the sand-reel 9 is hung. The frame 8 ismade of Figs. 7 and 7* are detail sec` fiat iron, the ends being bent at right angles,

as clearly shown in Fig. 4, the said ends be- ^ing Vbored to receive bolts by which the frame issecured to the plate 5. In the center of the topof the plate 8 is bored a hole to receivethe bolt 10, which also carries the diagonal support 11 and the sand-reel swinglever. The diagonal support has the effect of making the frame 8 more rigid and is bolted at its lower end to the plate 5. Se cured to the inside of the plate is a brakeplate 13, (see Fig. 3,) which serves to stop thc friction-pulley 14 when it is thrown out of engagement with the friction-wheel on the crank-shaft'.

In order to allow the bullwheel to be hung as low as possiblein the rig-frame, and in order that the `same might spool the required amount of cable for deep drilling, the plate 5 is made shorter than the corresponding plate,

to be hereinafter described, and the rear end d oft the same is provided with a downwardlyextending brace 15, which is mortised in the ,lower sill 3. (See4 Figs. l and 8.) The rear side of said rig-frame is constructed insub- Stantially the same way as the front side, having a lower sill 16, the rear end only of which is shown`,`(seeFig.'2,) and an upper plate 17, said upper plate being supported by upright posts and bolts similar to those already described.` The platel? carries at its rear end a pillow-block 18 `for supporting the back gudgeon of thebull-wheel. Centrally located on the plate 17 is a pillow-block for supporting the rear end of the crank-shaft similar to that for supporting the front end thereof, and between this bearing and the front end of the plate 17 is a third pillow-block, which acts as a bearing for the back gudgeon of the sandreel. Secured to the side of the plate 17, near its rear end, is a bar 20, which extends upwardly and out over the brake-wheel 21. This bar carries two downwardly-extending pins 20, which straddle the rim of the brakewheel (sce Figs. 2 and 6) and are adapted to prevent the brake-band from slipping therefrom. The frame-sills are spaced apart and held rigidly together by suitable blocks and bolts. The plates Sand 17 have a block 22 mortised therein and a bolt spacing them apart and holding them rigidly together. The

front gudgeon of the bull-wheel is supported rooV by a post 23, which is dovetailed into the rear cross-sill 2 and there bolted. The post 23 is also strengthened by a front brace 23a and also by front and back turnbuckle-rods.

The bull-wheel shaft 24 is of usual construction, save that the rear gudgeon 24a of the same is made integral with the sprocketwheel 25, which is bolted and keyed to the side of the brake-wheel 21 (see Fig. 6) by means of bolts passing through block 26, the brake-wheel 21, and brace-arms 21a, (clearly shown in Fig. 6",) squared against the bullwheel 24and bracing the brake-wheel 21. 'The sprocket-wheel 25 is further secured by means of key-pins 27 engaging perforations in the end of the bull-wheel shaft and by bolts extending longitudinally through the end of the bull-wheel shaft 24 to transverse cuts 24, (shown in dotted lines, Fig. 6,) the inner ends of the bolts being held by nuts in said cuts. The sprocket-wheel 25 is connected to the sprocket-wheel 28 on the crank-shaft 7 by a chain, as shown in Fig. 3. The sprocketwheel 28 is loosely mounted on said shaft, having a collar 28a on one side integral therewith and abutting against plate 17 and havking a iiange or hub 29 on the other side with a recess therein adapted to receive a projection or key on the clutch member 29, slidably mounted upon the shaft 7 and having a rigid feather 29c engaging a longitudinal slotor key-seat 7a in said shaft 7, said clutch member 29PL adapted to be thrown into engagement by a sleeve 30, (see Figs. 7 and 72,) carrying the feathers 31, which play in a slot 29h, extending around the periphery of the member 29a. The sleeve 30 consists in two spoon-shaped members bolted together reversely, each of said members carrying one of the feathers 3l, the end of one of said members projecting upwardly and pivoted to a bent bar 32, which is secured to the plate 17. The end of the other member extends downwardly and is secured to the hand-lever 33, which is pivoted at 34, and by which means the clutch is operated from the front of the rig. The brake-band 35 is bolted to a drawbar 36, which is connected at the front end of the frame with a hand-lever 37.

The sand-reel 9, the location of which has already been described, comprises a shaft 38, the ends of which act as gudgeons, around which shaft a casing v39 is itted snugly, a friction-Wheel 14 being mounted on the end of the shaft 38 and adapted to be thrown into engagement with the friction-wheel 40 on the crank shaft 7. This is accomplished by means of the swing-lever 41, at the lower end of which is pivoted a draw-bar 42, at the end of which draw-bar is a handdever 43, movably secured to the front vertical post 44.

45 is the Samson-post, upon which is pivoted the usual walking-beam. The Samson-a post is braced on one side bya two-inch round iron brace 46, on the opposite side bya turn buckle-rod, and on the rear side by a turn buckle-rod and a brace 47.

The band-wheel 48 is hung on the extreme rear end of the crank-shaft 7.

The derrick consists of two legs 49, which are made in sections and spliced together to obtain the desired height, the splices being held by the straps 50, (see Figs. 1 and 2,) secured by bolts. The legs are spread apart at the bottom and mortised into the mudsills at 51. They are drawn in at the top and spaced apart by a block 52, mortised into them, the block 52 being of suiicient length to allow the crown-pulley 53 to revolve freely. The legs 49 are also provided at their upper ends with the dead-line hooks 54 for the purpose of hanging a snatch-block 55 (shown in dotted lines, Fig. 2) when necessary. The legs 49 are also provided at their upper ends with the cross-pieces 56, (see Figs. 1 and 2,) which carry blocks 56a, which provide bearings for the gudgeons of the crown-pulley 53. The cross-pieces 56 are braced on their under sides. The two legs 49 are rigidly secured together by cross-beams and diagonal braces,

as clearlyshown in Fig. 2, which are bolted to the legs.

57 represents supports bolted to the legs and being mortised into the sill at the base of the derrick. The legs are also strengthened by turnbuckle-rods suitably arranged and being secured to pegs at the base of the derrick.

58 is the derrick-floor, with which portable drilling-machines have heretofore not been provided. This floor is suitably mounted in cross-sills, which are gained in the mudsills.

59 represents runners on the engine-block 60. These :runners are cut under at their ends and are so made to provide for the easy changing of the engine from one position to another without removing the same from the block.

Having thus described my invention, what l claim as nettr therein, and desire to secure by Letters Patent, ism

1. In a drilling-machine of the character described,the combination of a frame,a crankshaft mounted upon said frame, a band-wheel mounted upon said crank-shank, a sprocketwheel also mounted upon said shaft, of a bull-wheel shaft, a sprocket-wheel carried by said bull-Wheel shaft, one of the gudgeons of said bull-wheel shaft being mounted in one side of said frame, the other gudgeon being mounted in a post, one side of said frame being of lesser length than the other, to permit the mounting of the bull-wheel in close proximity to the ground and enable the same to spool the requisite amount of cable for deep drilling.

2. In a drilling-machine of the character described, the commbination with a frame having two sides, of a bull-wheel shaft having one of its gudgeons mounted in the end of one of said sides, and a post forming avbearing for the other gudgeon of said bull-wheel shaft, the other side of said frame being of lesser length than the flrst-mentioned side to IIO said shaft and bracing the brake-Wheel,of bolts passing through said sprocket-wheel,
